Heavy load high speed main spindle ball bearing 7072ACP5

The four point contact ball bearing 7072ac/b/c 360X540X82mm belongs to single row ball bearing.The bearing types commonly used in high speed grinding spindle are B70C and B70CA series, and B72C and B72CA series can also be used in heavy load. they can sustain significant axial loads in one direction together with radial loads. Because of their design, when a radial load is applied, an axial force component is produced; therefore, two opposed bearings or a combination of more than two must be used.
